[0031] It should be noted that the grid plate 801 is convenient to stick to the bottom of the gate plate 903.

[0032] Working principle: Through the setting of multiple treatment tanks 1, the sewage can be subjected to multiple chemical precipitations. The sewage enters the first treatment tank 1 through the water inlet pipe 3, a chemical agent can be poured into the treatment tank 1, and the rotating shaft 702 and the stirring rod 703 are driven to rotate by the motor 701 to stir and mix the sewage and the chemical agent, thereby accelerating the reaction speed and speeding up the chemical precipitation. After the chemical precipitation is formed, the precipitate falls on the filter cloth 802 at the bottom of the treatment tank 1.

[0033] After the precipitation is completed, the piston rod of the electric push rod 5 slowly extends, drives the L-shaped frame 6 to slowly rise, and further drives the grid plate 801 and the filter cloth 802 to slowly rise. The filter cloth 802 filters the sewage in the rising process, filters the precipitate and impurities, and leaves them on the top of the filter cloth 802. With the rising of the filter cloth 802, the precipitate is transferred from the bottom of the treatment tank 1 to the opening at the top of the treatment tank 1, which facilitates the cleaning of the precipitate from the filter cloth 802. The staff does not need to enter the inside of the treatment tank 1 for cleaning, which is more convenient.

[0034] In the rising process of the grid plate 801, the grid plate 801 contacts the baffle 904, drives the gate plate 903 to rise, and extrudes the spring 902. The rising of the gate plate 903 can open one end of the communication pipe 2. At this time, the sewage subjected to the first chemical precipitation is automatically discharged into the next treatment tank 1 for the next chemical precipitation after being filtered, without manual opening of the gate for water release, thereby further improving the convenience.
